The article deals with the comparison of Coleoptera of peatlands of Belarusian Land O˙Lakes (the area of Wurm glaciation). The research was carried out in 17 peat bogs during 1997-2006. 245 Coleoptera species were recorded in the natural raised bog. 209 species at meliorated bogs were recorded as well. 10 species are tyrphobiontic and 33 are tyrphophilous. There is low beetle species diversity however the species that are present are highly abundant. Agonum ericeti (Panzer, 1809), Cyphon congsbergensis Munster, 1924, C. padi (Linnaeus, 1758), Drusila canaliculata (Fabricius, 1787), Lochmaea suturalis (Thomson, 1866) are very common. The majority of species were recorded in open raised bogs. The maximum number and diversity of imago-beetles were recorded in May - early June. The overwhelming majority of beetles comprise of species with spring-summer type of reproduction and that, which hibernate on the imago-stage.
